Vertical type production unit for high-concentration Na131I solution

The invention provides a vertical type production unit for high-concentration Na131I solution; the production unit comprises a lifting platform, a distiller, a feeding platform, an iodine capturing device, a circulating water pump and a controller. The lifting platform is fixedly connected with the distiller; the distiller is respectively connected with the iodine capturing device and the circulating water pump by pipelines; the feeding platform is arranged below the distiller; the controller is respectively connected with the lifting platform, the distiller, the feeding platform, the iodine capturing device and the circulating water pump. The vertical type production unit for high-concentration Na131I solution is capable of automatically discharging distillation residues, or even, directly putting an uncovered target barrel into a ceramic crucible for distillation; the single yield of the unit and the concentration of the Na131I solution can be improved greatly and the radioactive contamination risk and the yield of solid wastes can be reduced. The production unit is compact in structure and applicable to the destructive distillation production for the high-concentration Na131I solution in a shielded working box with smaller effective operating space and is good in operating stability, convenience and safety.
